when it is full of water. A level concrete floor or pad is recommended.
BOILER INSTALLATION
Connecting the electrical supply to the Boiler:
Electrical Requirements:
120 V / 60 Hz
Single Phase
20 Amp dedicated circuit
WARNING: Shut off main power to the boiler before making any electrical
connections. ONLY a qualified electrician should run wire and make connections to the
boiler. All wires must be the proper gauge and run in approved electrical conduit. All
wiring must meet the requirements of the National Electrical Code.

BOILER INSTALLATION
Installing the chimney components:
WARNING: Double wall “Class A” insulated stack must be used through any building
penetration and for any exterior stack. Unapproved stack material and/or installation
can create a fire hazard. Contact Clean Energy Heating Systems, LLC to purchase
approved stack material for your installation.
CAUTION: Using single wall stack on the exterior of your building will cause the stack
gases to cool rapidly and adversely affect the natural draft of the boiler. This will create
a back draft and may damage critical burner components.
(1) Refer to Figure 10 for a typical through-the-roof chimney illustration and Figure 11 for a
typical through-the-wall chimney illustration.
(2) Observe the following requirements when installing the chimney:
• The CE-340 boiler requires 8” I.D. stack components.
• Have a minimum of 10 feet vertical chimney to ensure -.02” w.c. draft over fire.
• Keep horizontal runs short. Slope any horizontal sections at least 1/4” per foot.
• Keep the stack installation simple. Multiple turns and horizontal runs will reduce the
natural draft of the boiler which may damage critical burner components.
(3) Single wall stack may be used inside the building. Observe proper clearances from
combustibles. Do not put single wall stack in areas that may create a burn hazard to
personnel.
(4) Install a barometric damper, as shown in Figures 10 and 11, so that proper draft can be
maintained. Follow the instructions provided with the damper for proper installation.
(5) Use double wall “Class A” insulated stack when making a penetration through the roof or
side wall of your building. Install proper flashing around the exterior penetration of the
stack to make a water tight seal. Clean Energy Heating Systems, LLC recommends
“Dektite” flexible pipe flashing, or equivalent, for through the roof installations.
(6) Install a “Class A” non-restrictive stack cap only.
CAUTION: IF YOUR BUILDING UTILIZES AN EXHAUST FAN, ensure that there
is adequate make-up air available. Lack of make-up air will create a vacuum in your
building which will result in a back draft at the boiler. A back draft will damage critical
burner components.

Oil storage tank setup:
Figure 12: Typical Oil Storage Tank Installation
(1) Refer to Figure 12 for a typical oil storage tank setup.
(2) The tank must be installed according to all NFPA requirements and State and Local codes.
(3) An inside tank is recommended.
(4) Locate the tank in a position that will allow the oil pump to be mounted as close as possible
(5) Only use a tank with a drain on the bottom. Over time, dirt and sludge will naturally
accumulate on the bottom of the tank and there must be a way of removing this unwanted
material.
(6) Some state and local codes require the tank to be vented to the outside.
(7) Educate all personnel what substances are allowed to be added to the used oil supply and
apply the provided tank warning label near the fill location.
Installing the metering pump system and oil lines:
Metering Pump Installation Guidelines:
(1) Use non-hardening thread sealer for all threaded pipe fittings. DO NOT use teflon tape.
(2) The pump must be installed with the shaft in the horizontal position and the oil outlet
pointing up.
NOTICE: The gauge arrow on the front of the pump head must be pointing up.
CAUTION: The metering pump must be mounted above the oil tank. The pump is
not designed to take head pressure. If the pump is below the level of oil in the tank the
pump seals may begin to leak.

(3) The metering pump system is a fixed displacement pump. The pump shaft is driven by
a gearmotor at a specific rpm, for each specific model. This delivers a constant flow
(gph) of fuel. Change in oil viscosity and temperature have very little effect on fuel flow.
Therefore no oil pressure adjustment is needed for the metering pump system.
(4) The metering pump must be mounted as close to the tank as possible. The suction oil
line (length of oil line from the bottom of the tank up to the pump) must not exceed 8
vertical feet. Every 3 horizontal feet of suction line reduces the maximum allowable
vertical lift by 1 foot.
(5) The suction oil line must be a minimum of 8” from the bottom of the tank to reduce the
likelihood of sludge and/or water being delivered to the boiler.
(6) The metering pump system is not weatherproof. Mount the pump indoors only.
Mounting the metering pump assembly:
NOTICE: The metering pump system comes assembled for standard mounting on a wall.
STANDARD MOUNTING:
(1) Refer to Figure 13 for a typical metering pump installation (standard mounting on a wall).
(2) Use appropriate hardware to mount the metering pump system to the wall.
(3) Keep the pump assembly as close to the tank as possible.
ALTERNATE MOUNTING:
(1) Refer to Figure 14 for an illustration of the alternate horizontal mounting.
(2) Loosen the pump head and rotate it 90o. The pump assembly may now be mounted in the
horizontal position as on a shelf.
